This vintage hat was made by Resistol in the 1950s. It is rare to come across these early Resistol westerns, and rare to find cowboy hats like this with a bound brim. As you can see from the fade line, it originally had a mid-with ribbon, much wider than usually found on westerns of this era. It has the early Resistol Western liner (Before westerns became Resistol’s bread and butter) and a brown leather sweatband. It was originally sold by Wolf Brothers of Omaha, Nebraska. It is a size 7-1/4.

I have one I just inherited. Never worn. With this XdoubleX marking. Also has the “if you want to duplicate” statement. Original box with sales tag on hat and on box for $21.50 brand new. Also has a 3 color tag on the inside of the hat that says, “You have just purchased most comfortable hat made – a Resistol Self comforming hat. This exclusive inner band is suspended so that it conforms to your headshape – providing instant comfort and proper fit. No other hat has it! Flex the inner band. See how it floats free from the hat”. The box also has a handle taped to the back of the top of the box for something. Not sure what. Western black pinch front. Orange and black satin liner.
